> If someone turns up with matted hair, hasn't showered in months, and is wearing a pizza stained t-shirt then most companies won't want to hire them and most employees won't want to work near them. Such a person would probably stink, which is a sensible reason for employees not to work with them. Such a person also appears to demonstrate either being unaware of (very unlikely unless their sense of smell is broken and they don't have any friends who have told them it's a problem), or not caring about inflicting their stench on their prospective coworkers, which probably implies something bad about their judgment and considerateness, which is also a sensible reason not to hire them. If you never saw the person until hiring them, that could be an issue; but if it were a line item in company policy (maybe alongside the dress code) that employees shall not inflict a stench on others, then at least you could get on their case about it on day 1, and have a fully justified reason to fire them quickly if they didn't shape up. Of course it'd be more efficient to have not hired them at all, but there will always be some problems you just don't find out about until later. I don't think this particular failure mode is common.
